EFFECTS OF SPACE PARTICLE RADIATION ON INTEGRATE CHIPS IN THE SATELLITE

This paper analyses energy deposit in critical volumes of integrate chips, whi-ch produced by some radiated particles in Feng Yun-1 (B) satellite environment. That is called linear energy translation (LET). We have obtained the LETof Galactic Cosmic-Ray components 1 ≤Z≤28, Galactic Cosmic-Ray anomaly components (C, N, O, Ne, Ar, Fe), and inner radiation belt protons. And single event upset (SEU) ratioes produced by these particles are caculated respectively.
